Seed of the Week: Texas Ebony

Our mystery legume seeds from last week were from the Texas ebony tree, Ebenopsis ebano (formerly Pithecellobium flexicaule).

texas-ebony-side-of-treeThe Texas ebony tree, as its name suggests, is originally from Texas, but it also does well as a landscape tree in Arizona. It is slow growing, eventually becoming good-sized tree.

texas-ebony-branchAnother common name is “ape’s earring” because of the large, persistent seed pods.

The tree is also known for its lovely dark green foliage, much darker than most desert trees.

texas-ebony-seed-podAn unusual characteristic of Texas ebony is that the branches change direction at each node, giving an up-down zig-zag appearance. It also has thorns.

texas-ebony-flowersThe flowers are creamy-white puffs, similar to acacia flowers.

The bark is gray and fissured.

So, why is the tree called Texas ebony? It turns out the heartwood is dark red to purplish, sometimes almost black, so it resembles ebony wood.

Have you ever seen a Texas ebony tree?

Mystery Seed of the Week 206

 

mystery-seeds-206-1These mystery seeds are from a southwestern tree.

mystery-seeds-206-2The seeds are quite large, perhaps as big as the tip of your finger.

Do you recognize what plant these seeds are from? If you choose to, please leave a comment with your ideas.

New mystery seeds and Seed of the Week answers are posted on Tuesdays.

Seed of the Week: Mountain Ash Tree

Our mystery seeds from the orange “berries” last week were from a mountain ash tree, Sorbus sp.

sorbus-mountain-ash-seedsI thought probably the tree I took the seeds from was the American mountain ash, Sorbus americana, which grows in northeastern North America.

sorbus-hybridaThe seeds look closer to Sorbus hybrida, which is the oakleaf mountain ash (Photograph by Tracey Slotta @ USDA-NRCS PLANTS Database). On the other hand, the leaves and geographical distribution are all wrong.

sorbus-scopulinaWhat do you think about Sorbus scopulina, called Greene’s mountain ash (photograph by Steve Hurst @ USDA-NRCS PLANTS Database)? These are from western North America.

In all likelihood, these landscape trees are a cultivated variety that doesn’t match any of the above. They will remain a bit of a mystery, after all.
